I'm no expert, but I'd be suspecting the pump seals - when the hydraulic oil & pump warm up, the metal expands and if the seals are faulty they will not hold the pressure...
I'm sure someone else here will be able to give you more detailed advice - try looking for JJ...
It could be a filter in the closed center pump that can become clogged and prevent the pump from going into stroke, it could be the CC pump going out, or you likely have an OC "transmission" pump that feeds the main pump and lubes the transmission that could be going out.
